5 Claims.

This invention relates to' improvements in assembly' fixtures adaptedfor use in assembling and securing together the paper slips of amultiple-slip form.

Multiple-slip forms are used for many purposes and "are of differentcharacters. This invention is adapted for use in assembling and securingtogether the slips of a form made up'of a broad header sheet anda seriesof narrower slips attached to the header sheet and to each other alongone vertical marginal edge, the first slip projecting or "extendingslightly below the lower edge of the "header sheet 'and each additionalslip extendingaslight distancebelow the slip nextabove, the header sheetand all the attached slips being secured together inshingle arrangement.The header/sheet and the attached slips must be accurately aligned witheach other, and the area of the slips exposed at the 'face of the formmust be uniform. Many of these multiple-slip forms are used'inhectographing operations and the exposed portion of each slip receives aline or two of printed matter from the master hectograph sheet. It isobvious, therefore, that the header sheet and the attached slips must beaccurately aligned and the exposed portions of the slips mustbe'uniform' in size. In some instances the slips, after receiving thehectograph impression, are detached from the'header sheet and from eachother; It is important, therefore, that the slips be attached tothe'header sheet and to each other by adhesive lightly applied alongaportion of.- one vertical edge of each slip.

It is the object of this=invention to provide an assembly fixture bymeans of which the header sheet and the multiplicity of slips may bequickly and accurately assembled and aligned and secin'ed together alongonevertical'edge.

In the drawing, Fig. 1 is a planview of the ssembly fixture illustratingthe manner of securing the first slip to the header sheet;

Fig. 2 is a similar view of the fixture showing a number of the slipsassembled and attached to the header sheet and to each other;

Fig. 3 is a longitudinal vertical sectional View of the assembly fixturetaken on the line 3'3 of Fig. 1;

Fig. 4 is a perspective view of the multipleslip form complete; and

Fig. 5 is a detail View of one of the slips with the adhesive appliedready for assembly and attachment to the form.

The header sheet and the attached slips are secured together in reversedposition, that is to say, facade-W21.- When .the. form is complete it isremoved -from the assembly fixture and reversed in order to' bringit'into face-up position, as shown in Fig. 4.

The assembly fixture consists of a board or edges by the lower edges ofthe slips.

plate I having an upstanding aligning flange 2 along its left-handmarginal edge. Along the upper edge of the plate I is arranged an up-'standing aligning bar 3 adapted to be engaged by the upper transverseedge of a header sheet. The aligning flange 2 is adapted to be engagedby the left-hand vertical marginal edges of the header sheet and theslips as they are arranged on the fixture. At a suitable distancebelow-the aligning bar 3 and on the upper face of the plate I isarranged a transversely extending headersheet-aligning bar 4- whoseupper edge forms a gag-ingshoulder. This bar terminates a consid erabledistance short of the right-hand margin of the plate I. Thisbar 4 is ofconsiderable thickness and forms the lower edge of a large pocketbetween the aligning lea-r3 and said bar 4 for the reception-of thecomparatively large header sheet 5. It is desirable that'thi's bar be ofsuflicient thickness to permit the stacking in the pocket of asubstantial number of header sheets.

Below the header-sheet-aligning bar 4 are arranged a series ofslip-aligning and gaging bars 6 whose upper" edges form shoulders whichare adapted'tobe engaged by the lower edges of the slips;- Each bar Iiextends transversely of the plate I from thealigning flange 2 andterminates a substantial distance inwardly from the righthand margin ofthe plate 5. These bars are equal distances apart from each other andfrom thewbar 4. The distance between the upper edge of one bar and theupper edge of the next bar below it defines the extent of the exposedportions of the attached slips when the form is turned face-up as shownin Fig. 4.. Aligning and gaging-bars 6 project slightly above the uppersurface of the plate I and are preferably just thick enough to beengaged along theirupper These bars 6 terminate along a vertical lineleaving a smooth, unobstructedsurface onthe plate I at the right-handends o-fsaid bars. This flat, unobstructed surface along the right-handmargin of the plate permits the overlapping portions of the header sheetand the slips to lie fiat on the plate and on each other so that theymaybe readily secured together by adhesive applied to the slips.

When thefixture is in use a substantial number of the header sheets areplaced in the pocket formed by the bar 3 and the gage bar 4,'said sheetsbeing accurately positioned by the aligning flange'Z and by the bars 3and 4, Adhesive is applied to one of theslips 5 along a portion of itsleft-hand marginal edge as shown at X in Fig. 5. The adhesive is notapplied to that portion. of the left-hand edge of the slip which is toextend belowthe header sheet. The slip with the adhesive applied is thenreversed so that the adhesive is then on the under side of the slip atthe ill iii)

right-hand marginal edge. The slip, in this position, is then alignedagainst the flange 2 and the upper edge of the first aligning and gagingbar 6.

The edge of the slip bearing the adhesive is then pressed down at theright-hand margin of the header sheet which is in place between the bars4 and 3.

by the adhesive. After the attachment of the first slip to the headersheet as described, adhesive is applied to the second slip 5 asillustrated in Fig. 5 and that slip is then reversed, gaged and alignedby the second gage bar 6 and the aligning flange 2. The right-handmargin of this slip, to which the adhesive has been applied, overliesthe previously attached slip 5 and is pressed down on the saidpreviously attached slip. The flat, unobstructed marginal portion 1 ofthe plate I provides a smooth surface against which the right-handmarginal edges of the slips may be pressed to attach them firmlytogether by the adhesive. This operation of attaching the slips isrepeated until the desired number of slips have been secured. When theform is of proper length it is removed from the fixture and reversed sothat the attached edges are at the left-hand margin of the form, asillustrated in Fig. 4.

It is of advantage to provide means for stacking a considerable numberof header sheets 5 in the pocket between the gaging bar 4 and thealigning flange 3 as that facilitates rapid operation and renders itunnecessary to place a header sheet in the pocket for each multiple-slipform.
